FRANCIS J. TING, OF CLEVELAND, OHIO.

DRIER;

SPECIFICATION forming part of Letters Patent No. 563,348, dated July 7, 1896.

Serial No. 5 8 6,91 8. (No model.)

To all whom it may concern.-

Beit known that I, FRANCIS J. WING, a citizen of the United States, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in Driers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its objects the rapid drying or burning of garbage, refuse, or other material, the utilization of the heat of the fire to the fullest extent for these purposes,

and the consumption and elimination of the vfoul odors and offensive gases which will be produced during the drying or burning operation.

The invention consists in the construction and combination of parts for effecting these results, which are shown in the drawings and hereinafter described and claimed.

In the drawings, Figure 1 is a vertical section of a drying-kiln containing my invention, and Fig. 2 is a transverse section at the dotted lines 1 1 in Fig. 1.

Referring to the parts by letters, A represents the fire-pot inclosed by walls. The grate extends across the fire-pot, dividing it from the ash-pit a. The drying-chamber is above the fire-pot, and is entirely inclosed, except for the aperture for the stack H, by walls of brick, iron, or other suitable material. A perforated support D is supported within the drying-chamber and serves to divide it into the hot-air chamber B and the gas and odor chamber F. This support D is preferably circular, and is itself supported upon balls I) b, which travel in a ball-race c in the circular support E. The outer edge of the circular support D is provided with gears, which are adapted to mesh into the gears of the pinion-wheel O, which has its bearings outside of the drying-chamber, and is operated by any suitable power. Opportunity for the pinion-wheel to come in con tact with the outer edge of the circular support D is furnished by an aperture in the Walls of the drying-chamber. The support E is fastened and supported between the walls of the chamber B and the walls of the dome which inclose the drying-chamber on the top by suitable means, such as bolts and nuts.

The stack H is supported above and in connection with the dome I. Within the dome v I is provided a false dome M, which is sufficiently smaller than the dome I to leave the space N, which is separated from the dryingchamber by the connection P. This false dome is supported in position by the connec- 7 This pipe may be the hot-air chamber with the space N between the dome and the false dome.

d cl represent buffers which are adapted to revolve upon fixed axes and serve to keep the circular support D in position.

S represents a chute which passes through the walls of the dome I and the space N, and opens into the chamber F, and serves as a means of introducing garbage or other material to be dried or burned. This chute may be closed with a slide.

An opening or openings in the walls of the dome I are provided, as at T, at the line 1 1 for the discharge of material from the support D when sufficiently dried.

The operation of the described drier is as follows: Garbage or other matter to be dried or burnedis deposited in the chute S,and from thence falls upon the support D. The support'D being revolved by means of pinion- Wheel 0, the material is distributed upon the surface of D. The amount of aqueous vapor in the atmospheric air measures its humidity on its drying qualities. lVhen air charged with moisture is passed through an incandescent mass of coal or other similar combustible material, the moisture is first converted into steam. The oxygen of the steam thus formed is then unit-ed with the carbon of the coal in a process of combustion and the released hydrogen burns in presence of the free oxygen of the air. On this principle in my device the air which passes into the fire-box A is deprived of its humidity and becomes more eifective for the purpose of drying than in its normal condition. The heated air rises from the fire in the fire-box and fills the hotair chamber B and then passes up through the material to be dried upon the supportD. The vapors and inalodorous gases evolved from the material by the heat rise into the space between the false dome and the support D, called the gas-chamber, from which they are drawn by the blower into the pipe G and thence discharged intothe ash-pit or fire-box below. They are then drawn up through the fire, in which they are consumed and purified, into the chamber B. Some of this gas passes again over the same course, and some of it, mingled with the other gaseous products of combustion in the fire-box, passes through the fines or pipes L and into the space between the dome and the false dome, from which it escapes through the stack. By this arrangement a-sufiicient draft is furnished to support the fire in the fire-box A, and all of the malodorous vapors and gases are necessarily subj ected to the heat in the fire-box, and none of the malodorous gases and vapors which have not been subjected to the heat in the fire-box can escape into the outer air. This operation continues until the material is thoroughly dried or burned.

By having the support D rest upon ballbearings and having the pinion-wheel O which operates its motion move upon bearings outside of the drying-chamber, all danger of the mechanism bywhich the support D is moved being disarranged by the influence of the heat is avoided.

Having described my invention, I claim 1. In a drier, in combination, a fire-pot, a drying-chamber above the fire-pot having a dome-shaped top, a stack, a screen supported across said drying-chamber, an inner false dome or hood supported in an arch-shaped top above the screen, flues connecting the hot-air chamber below the screen with the space between the arch-shaped top and the inner false dome, a pipe connecting the top of the false dome with the ash-pit, and a blower in said pipe, substantially as and for the purpose specified.

2. In a drier, in combination, a fire-pot, a drying-chamber above the fire-pot, a stack, a screen supported across the drying-chamber, a false dome supported in said chamber above the screen and connected with the arch-shaped top, a pipe connected with said false dome and discharging .into the space below the firepot, said pipe having an opening which may be open or closed, a blower in said pipe, and fiues which connect the hot-air chamber below the screen with the space between the arch-shaped top and the false dome, substantially asand for the purpose specified.

3. In a drier, in combination, a fire-pot, a drying-chamber above thefire-pot having an arch-shaped top, a stack, a .false dome supported within the arch-above the screen, fines connecting the dryingchamber below the screen with thespacebetween the arch-shaped top and the false dome, a pipe connecting the top of the false dome with the ash-pit, and a blower in said pipe, and a circular screen sup ported across said drying-chamber,said screen being supported upon ball-bearings and being operated by a pinion-wheel having its bearings outside of the drying-cl1amber,substantially as and for the purpose specified.

In testimony whereof I afiix my signature in presence of two witnesses.
